allows you to perform basic arithmetic and bitwise operations on TypeScript numeric types
DISCLAIMER: This project is highly experimental and primarily exists to demonstrate what's possible at the limits of TS's type system. It seriously strains the TS compiler and may even crash your IDE.
| Type | JavaScript "equivalent" |
|---|---|
Add<A, B> |
A + B |
Sub<A, B> |
A - B |
BitShiftLeft<N> |
N << 1 |
BitShiftRight<N> |
N >> 1 |
And<A, B> |
A & B (bitwise) |
Or<A, B> |
A ๏ฝ B (bitwise) |
All these types are restricted to working with positive integers that can be represented with 6 or fewer bits (i.e., 0 - 63). The size restriction is due only to performance. I originally planned to support a full byte, but even that was melting the TypeScript compiler; Webstorm was constantly crashing. With that said, the code would easily scale when the TypeScript compiler can better handle deeply nested types.
I also had a working implementation of multiplication, but also for performance reasons, I had to comment it out. Check out the source if you're interested.
